.Beitknown that I, ROBERT S. BmrsoN,

citizen "ofthe United'States, and a' resiof West Paris, inthe county of 0xt"-=fo'rd*and State of Mdine, have invented a 'new Improved Wire-Embedding Tool,

bf' which the following is a full, clear, and

exact description.

is invention has relation to foundation lojf'to'ols tfor bee kee" rs and relates more particularly to ane ectric wire imbedder.

\The invention contem lates a simple and effeotive tool for embed ing wire in a foundation in a simple and expeditious manner.

As "a further "eat the invention contemplates"a wire em ding tool which may be {used in pairs or singly, and which in- -'c'l'ud'es means for insuring an even embed- *di nigi I e invention further contemplates a tool of the-character described'whi'ch 1S extremely simple in its construction, inexpensive to manufacture, and which is thoroughly reliable and highly 'eificient in its purpose.

With the above recitedand other objects in view, the invention resides in the novel construction, set forth in the following specification, particularl pointed out in the appended claims and il ustrated in the acaocompanying drawings, it being understood that the right 'is reserved to embodiments *other than'th'ose actually illustrated herein to the full extent indicated by the general meaning of the terms in which the claims.

are ex ressed and by variations in the phraseo o' of the same.

Referring to Figures l, 2,3? md 4bf the drawings, relatin' to thewpreimedflom of the invention, the tool consists of a slamk 10 provided at its free extrernity'with tegrally formed angular extensions j 11 and 12, saidshank s'ndextensions bei rpm-i ably constructedof metal-orany o' snitablematerial which is a conductorof electricity. The oppoeiteend of theshank 5.0

has mounted thereon a handle 13*of1fibar,

porcelain, wood, or any other suitable' nim' terial which is a'non conductor elec- 'trioity. The inner end of the 'hanfie 13 has mounted thereon a metallic "ring Miprovided with a rearwardly extending leg 15 apertured to receive a bmding which a binding nut 17 is mountedfolthe purpose of'attaching the terminal of-aeonduit wire 18 to the binding post. Therlng 14 is further provided with a rearwardly extending spring arm 19 carryi on'its inner side a contact member 20 whic isj-design'ed to coact with a contact 21 mountedpn the handle and extending-therethrough and into the shank 10. The arm 19 normallyjio rates to hold the contact member 20 out-0f ement with the contact member 21 and is designed to act asa switch -when manually depressed to bring the contact members into engagement. The angularly disposed extension 11 is provided with areduebd pointed extremity 22 threaded at its'bjuncture therewith, to receive an adjusting nut 23 constituting a shoulder. A secondfshoulder 24 is located adjacent the free end of the extremity 22,"and a metallic sleeve 25 having a bushing 26 of insulating material, is provided on the extremity 22 for sliding movement, a coiled contractile spring 27 being interposed between the bushing and the shoulder 23 for normallyeifecting a contact of the metallic sleeve 25 with'the shoulder 24. The metallic sleeve 25 is connected to the ring 14 b a conduit wire'28. Anubstantially U- aped guard 29 preferably formed of insulating material, is supported from the sleeve 25 by the spider-arms 30, said guard being normally located ad'acent the shoulder 24, at'the free end of t 0 extremity 22.

In use and operation of the tool, the wire vA, to be embeddedin the foundation B, is connected at one extremity with the termi- .27 operating to hold the sleeve 25 in contact with the. shoulder 26% thereby completing the circuit from the source of supply through post 16,

into the foundation B, until the guard 29 contacts with the upper surface of the foundation sulliciently to separate the head 25' from the shoulder 2% against the action. of the spring 27. This serves to automatically break the circuit, and thereby constitutes a depth gage to eilfect a uniform embedding of the wire it in its foundation. The nut 23 constitutes a means for obtaining various adjustments or the guard 28, to vary the depth at which the gage will be brought into operation for breaking the circuit.

'Another method of embedding the wire it is illustrated in Fig. 8, in which instance the wire 0 is disconnected from the end of the wire B and is brought into movable contact with the wire A whereby the tool hereto heat and imbed short sections of the wire tofore described may cooperate therewith A." As specifically illustrated the tree terminal of the wire C which leads from one pole of'the battery D is connected with a second tool which is illustrated in Figs. 5, 6 and 7.

Another method of embedding the wire A is illustrated in Fig. 8, in which instance the wire C is disconnected from the end of the wire B and 1S brought into movable contact with the wire it whereby the tool heretofore described may cooperate therewith to heat and imbed short sections of the wire A. As specifically illustrated the free terminal of the wire C which leads from one pole of the battery D is connected with a second tool which is illustrated in Figs. 5, 6 and 7. The tool is proyidedwith a binding post 15 extending through one side of the handle, and in electrical communication with the shank 10 The binding post has mounted on its outer extremity, a binding nut 16, which coacts with the terminal of a conduit wire C, for clamping the same to the binding post. The free extremity oi the extension 11 is provided with a bifurcated point 18*, and is threaded at 19 to receive and adjustably support thereon, a depth gage plate 20*. The bifurcated point is designed for the purpose of pulling the wire, to tighten it if the same should be loose. Where the and is connected to the bindingnae-note second tool illustrated in lt igurele is our ployed, in lieu of attaching the wire C to the end of the wire A, the tools are respectively held in each hand or the operator, with their points in contact with the wire it are progressi ely moved over short sections of said wire It. to heat and iinbed the same. The purpose providing the extension. 155 in the first mentioned tool is to admit oi sing the tool in corners, or close to the edge or the frame where the guard member would interfere with the same. When the extension 12 of the tool is being used, the circuit is completed through the arm 19 and contact members 20 and 21 by manually depressing the arm and releasing the same when the desired depth is reached. The threaded mounting of the depth plate 2.0 on the extren'iity 11 permits of an adjustment of the same thereon for obtaining various depths when the tool is used.

vlriaving thus described my invention, what l: claim is:
